SUBJECT:
LONG-RANGE RESEARCH PLANS Per your request dated August 13, 1979, the following is a list of long-range research objectives pertaining to water hamer.
1.
Prediction of Effects:
Assess the likelihood, the conditions for occurrence, and the potential severity of resultant pressure pulses and direct structural behavior and outcome of postulated water hammer evants.
!1ork appears to be needea to detennine the magnitude of pressure surges, the limits and the conditions required to cause rapid steam condensation in specific systems taking into account factors such as initial void fraction, inter-phase surface area, flor regine, amount of subcooling and super-heating, etc.
Fluid-structure interaction, where applicable and feasible, should be included in the study of water hammer effects.
For example, this should include development of analytical tools, exploratory and verification testing, and assessment of design modification.
The technical approach to be pursued may depend upon the system or component under study.
2.
flitigation of Effects:
Develop a methodology that can be applied to assess water hamer effects in nuclear power plants.
Peccanend means to reduce water hammer potential or to mitigate wt.ter hamer consequences.
